Do they play reggeaton? Are there rooms with different kind of music?

I was just there for "Calvin Harris, Friday Nights at the Omnia". There are 2 rooms. The smaller room plays hip hop. The larger, main room plays EDM. You have to walk through the smaller room to get to the main room. There's also a rooftop bar.

Two rooms, one is EDM and the other is Hip-hop.

No there are no different rooms here. Although there are different levels!
